Emissive shaders. Type a temperature in K and get a blackbody colour – that's how most shaders do it, and it's wrong for practically every real material. Kirchhoff's law fixes it. linkedin.com/pulse/thermal-l…

Elon Musk’s January 6 Moonshots podcast prediction of 100x gains in intelligence at a fixed model size was at the edge of plausibility when made, now it’s simply a fact. What next?
Qwen3.8 27B literally broke the SIZE → INTELLIGENCE curve. Look how far left it is in the optimal quadrant. Crazy that a 27B model is sitting on the Pareto frontier like that. This RESETS expectations for what you can run on consumer hardware.

AAA studios implement technically better cities. This runs poorly on a maxed out MacBook (faster than consoles, and way more RAM). It's impressive that AI can build such big scenes nowadays, but technically they are still far behind on what professionals can achieve.
AAA studios spend $200M on a city this good. Ours cost $1,500 and swapped Miami for SF within a week. An agent did it in a loop while we slept, now he's working on the traffic and pedestrian.

I am excited to announce Dr.Jit 1.4 and Mitsuba 3.9 which now feature GPU-accelerated compute/ray tracing on Apple Silicon. Significant optimizations in both projects accelerate tracing/code generation ~2x. They generate better code and have faster Python bindings.🧵

Hedged requests (apparently inspired by the Tail at Scale paper by myself and Luiz Barroso) applied within a single machine to replicating data across DRAM channels and issuing reads to all channels, using the one that comes back first. ~5-15X reduction in p99.99 read latency. github.com/LaurieWired/tails… Cool stuff, @lauriewired! Accompanying video forwarded to me by a friend, which is how I learned about it: youtube.com/watch?v=QFi2WVGf…

I've been working with Spherical Gaussians recently as a representation for irradiance in realtime raytracing. Ended up deriving quite a few new approximations relating to SGs and diffuse lighting. Ended up with something both cheap and accurate. Link below

This year, we managed to ship Python 3.14 support for uv and Ruff on the day of the stable release. A big lift from the whole team. We wrote up a guide on some of our favorite features from 3.14, and how they affect our tools.

Python 3.14 is out today! Here are my notes on the new release: simonwillison.net/2025/Oct/8… If you're an open source library maintainer who supports all current Python releases this also means you can drop 3.9 support now and start depending on features from 3.10, like match/case
